Abstract
This paper describes a new technology of very compact 800MHz band dielectric duplexer. We has developed a dielectric TM triple mode resonator, that consists of monoblock high K ceramics. By using this, a much size-reduced dielectric duplexer has been designed and manufactured at 800MHz band. The duplexer which has each 6 poles has elliptic function characteristics and low insertion loss of about 0.8dB, high attenuation of 90dB. The volume is about 222cc, that is 1/5 of conventional cavity duplexer. This duplexer is very useful for cellular base station.
